Greece Issues Cyberattack Advisory Amid Iran-Linked Threats

Greek companies, including shipowners, banks, and firms in transport, telecommunications, health, and energy, are scanning their computer systems for cyberattacks following a high-priority advisory from the Greece===National Cybersecurity Authority (Greece). This pre-emptive measure comes amid incidents linked to the Iran war, with an Iranian-linked hacking group claiming responsibility for a cyberattack on Stryker and Albania confirming a similar attack on its parliament. The advisory listed indicators of compromise, including IP addresses originating from Iran, and urged firms to review and block suspicious activity. While Greece has not yet found evidence of a significant attack, 'some sort of activity' has been tracked, and electronic interference with commercial ship navigation systems has surged around the Strait of Hormuz.
